Charge Redistribution in Clusters revealed by XFEL Photoelectron Spectra — •Abraham Camacho Garibay, Ulf Saalmann, and Jan-Michael Rost — MPI-PKS, Dresden

Photoelectron spectroscopy in the sequential regime is usually expected to produce a plateau in the energy spectra for direct electrons of sufficiently high energy. This has been shown to be no longer the case if the cluster potential is high enough to trap the innermost emitted photoelectrons, but this effect appears to be hard to measure. We study a new case where field ionization sets in due to a deep cluster potential, this makes the charge distribution inhomogeneous, showing itself in the photoelectron spectra.
